I don't think there is a difference between SOC steppings and PCI ids from display and graphics perspective.
As in all the SOC steppings that share the same PCI IDs have the same display and graphics stepping.
But I do agree with you that changing the index to numeric PCI IDs perhaps removes ambiguity and makes it
consitent with the tables used for earlier platforms. I have sent a v2 addressing this change.
